V.O.D What do the kidney’s do? Main Functions? https://www.youtube.com/watch?v=FN3MFhYPWWo
Learning Intentions I can list and explain the main functions of the urinary system I can define osmoregulation and excretion I can describe the reactions that produces metabolites (nitrogenous wastes) and steps the body takes to eliminate them. Students read through notes Highlight and underline new words Have a partner ask you questions that you read about
Main Functions Of Urinary System Excretion Filters out metabolites and eliminates them from the body through kidneys. Maintain ionic and osmotic equilibrium.
Main Functions Of Urinary System 2. Maintaining Water-Salt Balance Regulates the concentration of NaCl in the blood which controls blood volume (due to osmosis) and blood pressure (due to blood volume).
Main Functions Of Urinary System 3. Maintain pH Levels Can secrete H+ or reabsorb HCO3 to increase/decrease pH as needed.
Main Functions Of Urinary System 4. Hormone Secretion Secrete Renin: causes release of aldosterone from adrenal glands, which increase absorption of Na+ by kidneys.
Learning Activity: what do you think of lab created kidneys? Read article Underline and define key words Discuss what you read with a partner Develop 2 new questions that you now have
